To all 'whom 'it may concern:

Be it knownlthat. I, STANIs'rAw Lannzni, subject of the Czar of Russia,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented i certain new and useful `Improvements inyHot-`Water Heaters; andI do declare the j heater.

` heating tank above the stove, an outlet from claimed said superheatingtank, an inlet into said water back and a `plurality of pipes estab``lishing'communication between said water back `and said superheatingtank. With the above object in view, my invention resides `in thefeatures of construction and [combination herein described and and shownin; the drawings wherein :f-

`Figure 1 is an enlarged vertical section through the range and heatingtank; Fig. 2 isa horizontal section on thefline 3-3 of Fig. `1; Fig.` 3is a perspective view of the water back; Figs. 4 and 5 are detailhorizontal sections taken on the lines 5-5and (S4-G `of Fig. `lrespectively; Fig. 6 is a horizontal section showing `a different formof watervback for application to a stove constructed for the use of bothgas and solid fuel`;`-Fig.`7 is a perspectiveview of the water backremoved; and Figs. lSand 9 are transverse sections taken upon the lines9 9and10-g-10ofFig.7." j In the i'irst five figures of the drawings, Ihave shown my inventionas applied to a cooking stove or range R, saidrange comprising the usual rectangular casing C, firei boXF, oven O,smoke discharge opening o, smoke flue 7 leading from the fire-box tosaid smoke discharge opening, `a fue] supply door D` into the upper endof said fire-box,

a draft damper D above the door D, and a door d into the oven.

The construction of the stove forms no part of the present invention butit is expedient, in order to render the proper coaction possible, thatthe fire-box F should extend transversely across the upper por-Specication of Letters Patent.

tion of one 'end of the stove and that the opening o be formed in therear portion of the top of said stove.

y Comingnow more particularly to details of the invention, the numeral 1designates a hollow rectangular water back which is applied to therearside of the range R and i i completely takes the place of the usualmetal back therein. i'lfhe back 1 is provided, on one of its uppermostcorners, with a forwardly projecting rectangular extension 2, saidextension being also of hollow eonstruction and communicating at itsforward end with the interior of a hollow rectangular portion 3whichextendstransversely inward therefrom and underlies the door openingwhich `is normally Vclosed by the door D. `When the parts are in properpol sition, theunder sides of the portions 9. and 3 rest upon the grateG and are supported by any'suitable fastening means. The up` permostportion of the back lis provided,`

preferably at `its central portion,` with a substantiallysemi-cylindrical extension 4 which projects rearwardly therefrom andthus forms a substantially semicylindrical smoke i passage j 5 whichterminatesfilush with the bottom of the smoke flue f, atlits lower end,`while its upper` end communicates with the rcarmost portionof theopening o. As` clearly shown in Fig. `1, the in-` ner and outer wallsofythe water back 1 are so spaced as to provide acirculating passageentirely around the rear wall of the smoke passage 5. By thisarrangement and consti-notion of the water back and its vay riousextensions, a large heating area is provided. all heat within the oven0, the fire-box'F and that passing `through the flue f, being utilizedfor the purpose oi heatingtheywater in said water back.

Rising from` the` top of the range R and disposed above the opening o,is a cylindrical super-heating tank 6, said tank having upper andlowerpartitions 7` and 8 which are connected by smoke flues 9, saidpartitions forming upper and .lower smoke chambers 10 and 11. thechamber 11 being located directly over the 'top of the range and thechamber l0 being closed by a solid top 12 and havingr a dischargeopening 13 between and projects upwardly through the chamber l0 andthrough the top 12, said pipe Vbeing connected by means of an elbow 17to a hot water discharge pipe not shown.

For the purpose of admitting water into the interior of the back 1, Iemploy an inlet pipe 19 which leads from any suitable water pressuresupply and is provided with a cut 0E valve 2O adjacent its connection`to said back. When the valve '2O is opened, the interior of the back lwill of lcourse be filled with water which will now become heated fromthe action of the heat from the stove as before described. It is a wellknown fact that heated water will rise and therefore I have provided aplurality of pipes 21 which enter the offset portion I ofthe back 1 andthe interior of the tank 6, between the partitions 7 and 8, said pipesentering these parts at differentl levels as clearly shown in Fig. 1.Thus it will be seen that the heated water will rise through said pipesand into the interior `of the superheating tank 6 where it will befurther heated by the action of the smoke passing upwardly therethroughand will then rise through the pipe 16 and will flow into the outletpipe. From the` outlet pipe it may be conducted, through suitableconnections, to a number of radiators from which it then returns to thepipe 19 through return pipes which lead froml the various radiators to amain return pipe which may be connected, between thevalve 20 and theback 1, with the pipe 19. Thus it will be i seen that the water, heatedby the parts mounted upon the range It, will circulate through thevarious feed and return pipes and the radiators disposed therein andwill again return, to the interior of the water back 1L to. be reheated.

I intend to not only employ my improved heating system for the purposeof furnishing heat to the various radiators,lbut to also supply hotwater to the .various sinks, washstands and tubs in the building. y i y1rWhen any one of the spigots is opened, it will be readily seen thatsome of the. water within the system will be exhausted. During the dayhowever, the valve 2O is left open andthe water, under pressure,vflowing through the pipe l19, will immediately reill the entire system.In case the watery within the system becomes overheated and abnormallyexpanded, the pipe 19 willjalso serve as a partial outlet therefor andwill prevent bursting of certain parts of the system.

Ialso provide the ashpit of the stove with an outlet funnel F `wherebythe ashes may be conducted to the basement.

In Figs. 6 to 9 inclusive, I have shown the form of water back which Imay Well Vemploy in connection with a cook stove hav'- ing a portion forthe use of gas and also a hre-box for consuming wood or coal. Inapplying the waterback to this form of stove, I construct the saine insuch a manner as to provide a rectangular portion 50 for insertion intothe lire-boXthe side and end walls of said portion beingof hollowformation, the rear end wall 51 forming the rear end of the fire-box Fwhile the front wall 52 is notched upon its upper end as indicated at 52in order that no obstruction may roccur between the draft controllingdamper plate P and the interiorof the fireboX. The innerwall 53 oftherectangular portion 50, is reduced in height at its rear end and isprovided with a laterally extending portion 54 which is ofsemifvcircular `contour at its yrear end and is entirely surrounded byan 'upright wall 55,' the eXtension 54, the wall 55 and in fact, theentire structure, so far described, being of hollow formation, thusproviding a large heating area for the water which is fedv theretothrough an inlet pipe 19 kand is discharged therefrom through a numberof outletpipes 21 from which it enters ythe superheating tank 6 in thehereinbefore described manner. By constructing the device in the lastdescribed manner, it will be seen that a rear! wardly extending portionof substantially semi-cylindrical contour is provided, `said portionresembling the portion I of the previously described form of theinvention and that the space between thev lateral extension 5t and thetop of the stove, constitutes an outwardly and upwardly extending draftflue. When this form of theinvention isjin position upon the stove, thesemi-cylindrical 190 a comparatively simple yet` extremelyfefli-A ycient heating system and have provided means which compensate foroverheating of the water and which serve to keep the sysi tem fullat'all times. i f

- I ymay here explain that I provide a pluralityof pipes E21, connectingthe water back 1 ywith thesuperheating tank 6, for the purpose ofpreventing thelsystem from hammering, said ypipes eifectually overcomingthis objectionable feature.

Although I have described my invention with considerable minuteness, Ido not wish to be limited to details of construction and arrangement ofparts otherwise than as ainpliiied in the appended claims. y

Having thus described my invention, what I claim as new and desire tosecure by Letp y ters Patent is 1. rIhe combination with a range, of awater back forming the entire rear side thereof and having a portionpartially surrounding the iire-boX of the stove and having a rearwardlyprojecting extension, a superheating tank disposed above the smokeoutlet of said stove and having upper and lower smoke chambers and anintermediate water receptacle, a smoke passage leading from saidextension through said tank and discharging near the upper end thereof,a water passage from said water back to said superheating tank, anoutlet from the latter and an inlet into said back.

2. The combination with a range having a smoke outlet opening in therear edge of its top and a laterally extending smoke flue incommunication with said opening, of a water back affixed to said rangeand forming the entire rear side of said range and underlying said top,said back having a portion partially surrounding the fire-box thereofand a substantially semi-cylindrical extension at the rear side of theback and underlying the rear portion of the smoke flue.

3. The combination with a range having a smoke outlet opening in itstop, a water back forming the entire rear side of the stove and having aportion partially `surrounding the fire-box thereof, a substantiallysemi-cylindrical extension projecting outwardly from the upper edge ofsaid back, said extension forming a substantially semicylindrical smokeflue disposed beneath the rear portion of said opening, a cylindricalsuperheating tank disposed above said opening and havingsmoke chambersin its upper and lower ends and a water receptacle between the two, anoutlet from the top of said receptacle, a number of smoke fluesestablishing communication between said smoke chambers, the lowermost ofthe latter being closed by the top of the stove and the uppermost havinga smoke outlet, and a pipe forming communication between the waterchamber of said tank and said semicylindrical extension.

4. The combination with a rango having a smoke outlet in the rearportion of its top,

of a water back constituting the back to the fire-box and having aportion partially surrounding the same, a substantially semicylindricalextension on the rear side of the back and underlying the rear portionof the smoke outlet, said extension forming communication between thefire-box and the outlet.

5. The combination with a range having a smoke outlet in the rearportion of its top, of a water back constituting the back to thefire-box and having a portion partially surrounding the same, a hollowsubstantially semi-cylindrical extension on the upper edge of the back,said extension being united at its lower end with the back by aninwardly extending wall and its upper end and inner side being open,said upper end underlying the rear portion of the smoke outlet.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
